Abstract

The main purpose of Hot Mix Asphalt (HMA) is to choose the most suitable and the most affordable mix of bitumen and aggregates, so that it can maintain the technical properties of the asphalt concrete in certain amounts. Different methods have been suggested for mixing the Hot Mix Asphalt (HMA) including the Marshall method, the modified Marshall method, Hveem method, and the Superpave mixing method. Concurrently, the project of mixing Hot Mix Asphalt (HMA) in Iran is done based on the Marshall method and the modified Marshall method. Regarding the weaknesses of the asphalt mixes in different situations, the engineers try to modify and improve the properties of the asphalt mix by use of different additives. On the other hand, the additional expenses of various additives to the asphalt mix for building one kilometer of the road is a negative parameter. However, by use of the additives, the technical properties of the asphalt mix improve. Therefore, to decide on a proper choice out of the alternatives would be a difficult task. This paper, tries to provide an appropriate method for evaluating and choosing the best alternative by taking into consideration all the technical criteria. In this article, we first evaluate the score and the weight of each alternative in each criterion. Then, the weight of each criterion is evaluated using the best-worst method, and eventually, taking all aspects into consideration, the rankings of different alternatives will be determined based on two situations: certain situation and uncertain situation.

最佳-最差法在获得初级改性沥青混合料中的应用

热拌沥青(HMA)的主要目的是选择最合适和最实惠的沥青和集料混合料，使其在一定的量下保持沥青混凝土的技术性能。热拌沥青的混合方法有Marshall法、改良Marshall法、Hveem法和Superpave混合法。同时，采用马歇尔法和改进的马歇尔法在伊朗进行了热拌沥青(HMA)的混合工程。针对沥青混合料在不同情况下的弱点，工程师们试图通过使用不同的添加剂来改变和提高沥青混合料的性能。另一方面，修建一公里道路所需的各种沥青混合料添加剂的额外费用是一个负参数。然而，通过添加剂的使用，沥青混合料的技术性能得到了改善。因此，要在各种选择中作出适当的选择将是一项艰巨的任务。本文试图在综合考虑所有技术标准的基础上，为评价和选择最佳方案提供一种合适的方法。在本文中，我们首先评估每个标准中每个选项的得分和权重。然后，采用最佳-最差法对各指标的权重进行评估，最终综合考虑各方面因素，根据确定情况和不确定情况两种情况确定不同方案的排名。

期刊介绍： The Electronic Journal of Structural Engineering (EJSE) is an international forum for the dissemination and discussion of leading edge research and practical applications in Structural Engineering. It comprises peer-reviewed technical papers, discussions and comments, and also news about conferences, workshops etc. in Structural Engineering. Original papers are invited from individuals involved in the field of structural engineering and construction. The areas of special interests include the following, but are not limited to: Analytical and design methods Bridges and High-rise Buildings Case studies and failure investigation Innovations in design and new technology New Construction Materials Performance of Structures Prefabrication Technology Repairs, Strengthening, and Maintenance Stability and Scaffolding Engineering Soil-structure interaction Standards and Codes of Practice Structural and solid mechanics Structural Safety and Reliability Testing Technologies Vibration, impact and structural dynamics Wind and earthquake engineering. EJSE is seeking original papers (research or state-of the art reviews) of the highest quality for consideration for publication. The papers will be published within 3 to 6 months. The papers are expected to make a significant contribution to the research and development activities of the academic and professional engineering community.
